R27 oil dipstick diameter?

[† Will]

Hello,
I have a problem with the oil level dipstick on my R27. The dipstick does not screw in to the crankcase - it just drops in without holding. The dipstick from my R25/3 does not fit either.

My question is - are the dipsticks for the R25 a smaller thread diameter than the thread on an R27 oil level dipstick?

I notice that the oil pump slotted tops are a different size to each other with the R27 (Vin No. 380533) being larger.

Many thanks if you can assist.

Hi Will,
the thread should measure: 26 x 1,5 mm
For both R25/3 and R27.

Thank you for the information Rolf.

Thank you for the measurements Rutz. The threads on the dipstick are completely stripped off and I need a new one. I hope the thread in the crankcase is good enough. Now I have an accurate measurement I can check it tomorrow.
The "fully restored"  machine has many faults and is not as good as it first appeared to be.
